Tokar [57] ABSTRACT The invention is a display package-reflector assembly for use with a cylindrical chemiluminescent light generating device. In the display mode of the assembly, the device is protected in a carton which is releasably secured to a display card that incorporates printed information about the light source and instructions concerning use of the assembly in its reflector mode. The display card also has a light reflective surface, and in the reflector mode of the assembly, the carton is fitted through holes formed in the display card which is thereby bent into a quasi-parabolic reflector with the light reflective surface on the concave side thereof. in use, the light source is mounted in a device holding means on the carton and thereby is held in the focal region of the reflector.

10 Claims, 9 Drawing Figures PACKAGE AND REFLECTOR ASSEMBLY FOR A LIGHT SOURCE SUMMARY OF THE INVENTION The invention relates generally to a package assembly for a chemiluminescent or chemical light generating device. The assembly has two modes of use, the first being for protecting and displaying the light generating device on sale, and the second being for efficiently reflecting light generated by the device to a point of use.

Chemical light generating or lighting devices of the kind contemplated herein are known and are disclosed in detail, for example, in the US. Pat. No. 3,576,987 issued on May 4, 1971 to Voight et al. Such devices emit cold light generated by a chemical reaction between suitable components separately stored in the device. Upon mixture of these components, the light is generated by a chemical reaction of the components. The reaction continues for a period of several hours, at which time the device burns out. Such devices are made of disposable materials and are preferably cylindrical in shape, with the ratio of cylinder axis length to diameter being several times larger than unity, so that mixture of the separately stored components is facilitated.

It is contemplated that chemical lighting devices of the aforesaid kind can be advantageously used in situations where emergency lighting is required, for example, in the home during a power failure, on a poorly lit road at night when emergency automobile repairs are being made, and the like.

For such purposes a reflector assembly is desirable, and because consumer oriented economics mandate that the cost of the reflector assembly be minimal, and because the device cannot be reused once it is burned out", ideally the reflector assembly would also be disposable.

Furthermore, chemical lighting devices of the kind referred to are but recently introduced to the market place. Accordingly, the ultimate consumer must be educated in the use of such devices; the present invention contemplates that sufficient instructional material can be incorporated with or printed on the packaging material used to market these lighting devices.

It is, therefore, an object of the present invention to provide a novel light and reflector packaging assembly for a chemiluminescent light generating device or source of the kind identified, said assembly serving to display that product, to instruct the ultimate consumer in the use thereof, and to furnish components of a disposable reflector to be assembled by the ultimate consumer for use with said light source.

In accordance with the invention, a chemiluminescent light and reflector assembly package for use in displaying a chemiluminescent light generating device for sale and for reflecting light developed by said device in operation comprises a flexible sheet having a light reflective portion on at least one surface thereof, a receptacle member releasably adhered to the sheet and a chemiluminescent light generating device disposed within the receptacle member, the package being rearrangeable to an illuminating assembly wherein the receptacle member engages the sheet to maintain the latter in a curved reflector configuration with the light reflective portion on the concave side thereof, and wherein the chemiluminescent device is held by the receptacle member in a light projecting position relative to the light reflective portion of the sheet.

' DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION Referring to the Figures, there are shown exploded perspective views of the various components, (FIGS. 2, 3) of one embodiment of an assembly package, (FIG. I) constructed in accordance with the present invention. These components, as assembled by the manufacturer for shipment to a marketing outlet, are in the form of a unitary package. (FIG. 1), generally indicated at 10, referred to herein as the product-display or display mode of the assembly package. The same components when properly rearranged by the ultimate consumer of the light source, form an illuminating assembly generally indicated at 11, (FIG. 4) for the chemical lighting device I2, referred to herein as the reflector mode of the assembly package.

With reference to FIGS. 3, 6, the chemical lighting device 12 is of elongated cylindrical shape, and has a body portion 13, an end cap 14 and a base 15 from which protrudes a tapered tongue 16. A hole is formed in the tongue so that, if desired, several devices can be strung together for use independently of the illuminating assemblies. The body portion 13, cap 14 and base l5 are extruded from light transmissive plastic, for example, polyethylene.

As set forth in more detail in the above identified patent, the chemical compounds for producing chemiluminescent light are separately stored and scaled within the body portion 13. In one form of the lighting device, one chemical compound is contained within a small glass capsule 17, (FIG. 6) which is emersed in the remaining required compound or compounds. The size of the capsule 17 is determined generally by the amount of compound contained therein. To activate the lighting device, the body portion I3 is flexed to a degree sufficient to break the glass capsule l7, and then shaken to mix the compounds, which chemically react to generate chemiluminescent light which is transmitted primarily through the body portion 13, and to a 3 lesser extent through cap [4 and base of the device. lt is of course to be understood that the chemical lighting device, its construction and operation, per so, are known.

During manufacture of the assembly package identified generally as 10, the lighting device 12 is wrapped in aluminum foil 120, (shown only in FIG. 3) plasticized foil, or other known wrapping material, disposed, and protected within a receptacle member or suitable protective container, shown as a carton means 18 which can be a conventional full-overlap seal-end carton, a partial overlap seal-end carton or a tuck-end carton. As illustrated, the container or carton I8 is rectangular in shape, although it is contemplated that other elongated receptacle member configurations may be used. The carton 18 is pre-scored on one side thereof, (indicated at 19 in H05. 1, 2) and slotted on the other side, (indicated at 20, 20a in FIG. 3), the pre-scored portion 19 and slots 20, 200 being aligned and of size sufficient to serve as a device holder or holding means for the base 15 and tongue 16, respectively of the lighting device 12, for the purpose more fully described be low. It will be understood by those skilled in the art that the device holding means formed in carton 18 can be proportioned for receiving the end cap 14 of the device 12, instead of the base end; in this case. a pre-scored portion like l9, for example, could be provided in place of slots 20, 20a, to receive the end cap 14 of the device, or the slots 20, 20a omitted, without any thing being substituted therefor.

The assembly package 10 additionally includes a flexible sheet having a light reflective portion on at least one surface thereof; as illustrated, the sheet can be a display board or display card means 21, one side 22, (FIGS. 1, 2), of which has advertising materials and instructions for use printed thereon and the other side 23, (FIGS. 4, 7), of which has a light reflective surface. As illustrated, (FIGS. 4, 7) the display card 21, which is to be used in an illuminating assembly 11 as a light reflecting element for the device 12, has one dimension, (indicated as L in FIG. 7), which preferably is substantially equal to the length of the lighting device 12. It is to be equal to the length of the lighting device 12. It is to be understood that for efficient reflection, the dimension L" is related to the light reflective portion of the flexible sheet or display board 21 and should be at least equal to the length of the lighting device 12. That dimension L" can be larger, but the improvement in brightness gained by an significant increase in the dimension L" is negligible. On the other hand, any significant decrease in the dimension L adversely affects the desired light distribution, because a significant amount of light is radiated past the light reflecting element, and is not focussed thereby in the desired mannerv In one preferred embodiment of the invention, the flexible sheet is reinforced and is made from rolls of heavy paper and aluminum foil, which are laminated together and cut into sheets of printing press size. The sheets are printed on the non-foil side and cut to display card sheet size. During the cutting operation, a plurality of spaced mounting hole forming portions, for example, die cut scored portions 24, 25 are formed on the display card 2], for the purpose more fully described below. Alternatively, the areas 24, 25 can be punched out of the sheets during cutting thereof into the display card sheet size.

Then, an individual lighting device I2 is disposed in its respective receptacle member, carton 18, and the carton relcasahly affixed, for example, by adhesive, to a display card 21 to form a unitary package, the pro duct-display mode 10 of the assembly package.

The assembly package is rearrangeable by the ultimate consumer who uses the assembly package in its illuminating assembly or reflector mode H. The consumer releases the carton 18 from the display card 21, removes the lighting device 12 from the carton and activates the device. He punches out the scored portions 24, 25 from the display card 21, (if corresponding holes are not cut therein during manufacture) and inserts the carton 18 into the holes formed by removing the scored portions 24, 25 of the display card 21, in such manner that the display card 21 is curved about an axis (FIGS. 4, 7) into a reflector configuration with the light reflective surface 23 symetrically disposed on the concave side thereof, and the mounting hole forming portions 24, 25 disposed at opposite sides of the axis To effect insertion, the display card 21 is preferably curved around the axis F into a substantially parabolic or quasi-parabolic surface, as best shown in FIG. 4. As is illustrated in the drawings, (FIGS. 2, 4, 7) the size of the carton mounting holes or openings 24, 25 in the display card 21 is substantially the same as the size of the crosssection of the ends of carton l8; proper orientation of the carton [8 places the prescored portion 19 of the light generating device holder higher up in the concave reflector region than the slots 20, 20a thereof.

The base 15 of the lighting device 12 is inserted through the scored portion 19 and slot 20, or slot 200, (FlGS. 2, 3) of the carton [8 with the tongue 16 of the base 15 extending through the slot 20, or the slot 20a. (As illustrated in the drawings, the tongue 16 extends through slot 20; rotation of the device 12 through l around its longitudinal axis enables use of slot 200 instead of 20.) The size of the carton 18 and display card 21 and the location of the scored portions 24, 25 in the latter and scored portion 19 and slots 20, 20a in the former are pre-selected so that when the carton 18 is inserted into the display card 21, (as shown in FIGS. 4, 7) and the lighting device 12 mounted on the carton 18, in the device holder means thereof, a spatial orientation is imparted to the lighting device 12 thereby locating it in a light projecting position relative to the light reflective portion 23 of the display card 21, preferably at the focal region of the quasi-parabolic reflector surface 23 of the display card. (Alternatively, the end cap 14 of device 12 can be seated in the pre-scored portion 19 of carton 18, to rest against the carton side which incorporates slots 20, 200. it is to be understood that slots 20, 20a can be omitted, and replaced by a second pre-scored portion like 19, to receive the end cap 14 of device 12.) This orientation increases the amount of light focussed at a given direction and distance by from about 3 to 5 times as compared to the amount of light obtained from the device at a given di rection and distance in the absence of the illuminating assembly 11. Further increases in light focussed at a given direction and distance can be obtained by providing additional reflector surface in the region adjacent to the end cap 14. Such additional reflector surface (not illustrated) can be any one or more of the conventional conic sections, provided for example in the form of reflective material auxiliary to the display card 21 or reflective material 12a wrapped around or shipped with the lighting device 12 in carton 18.

We have found that a parabolic or quasi-parabolic reflecting surface is the optimum conic section or shape for use in focussing light radiated from the elongated chemiluminescent device. However, it is to be understood that adequate light reflection can be obtained if the display card is bent for example into a cylindrical shape, although in this event. the chemical lighting device will no longer lie along a clearly definable reflector focal region.

It will be appreciated that as full a description of the aforesaid manipulative procedures to be carried out by the ultimate consumer, as is required or desirable, can be printed on the display card 2] surface 22.

Furthermore, referring to FIG. 8, it will be understood that the display card 21 can be manufactured by conventional techniques as a fifth panel 210 of carton 18. The line 26 where the fifth panel" 210 joins the carton I8 is preferably scored or perforated to facilitate separation of the carton l8 and display card.

In addition, referring to FIG. 9, other equivalent arrangements of display card 2] and carton 18 in the illuminating assembly or reflector mode of the assembly package can be provided, for example instead of inserting the receptacle member or carton 18 into mounting holes on display card 21, die cuts 27 of suitable size can be formed in the carton 18 to serve as pre-selected mounting locations for the display card 21, which when inserted into the die cuts is curved about the axis F with its light reflective portion symetrically disposed on the concave side thereof.

Moreover. provision of a reflector surface by means of a display card can be omitted, and in its place, a plasticized aluminum foil of appropriate dimensions is wrapped around the lighting device prior to sealing it in carton 18. The ultimate consumer then mounts this foil on the carton, or inserts the carton through pre-cut portions of the plasticized aluminum foil in such manner as to form a curved reflector surface of the shape described above with reference to FIG. 4. Sufficient instructions as to use in this instance preferably can be printed on one side of the plasticized foil and on the carton 18.

Thus, as set forth above in detail, a simple, inexpen sive and novel assembly package for a chemiluminescent light generating device which serves in one mode as a means for displaying the device on sale and in another as an efficient inexpensive illuminating or reflector assembly for that source in use, is disclosed in various embodiments.

It is to be understood that, while specific embodiments of the invention have been described as shown in the Figures, variations in structural detail within the scope of the appended claims are possible and are contemplated. There is no intention, therefore, of limitation to the exact abstract of disclosure or the specific embodiments described.
